Is flat frequency response desirable?

Do you think that same low level noise does not invade the analog circuitry in the PC itself, feeding the audio/headphones out on the typlical cheap analog circuitry built into most pcs. Even if at a very low, subliminal-like level, it still affects the audio signal. Not exactly high-fidelity. You REALLY need to get out more. The Lynx 2 is one of the quietest audio interfaces that there is. A LOT more quiet than most so-called stuff that's labeled "high-end" which is often pretty noisy in comparison. I know - I've tested a lot of it and this is provable, both objectively and empirically. Funny (in the strange sense) that you don't mention the acoustic noise from the fans, which IS a real problem, but solvable. I get around it by using a fanless power supply, an efficient low speed fan for the CPU and putting the machine in a nearby closet. And how many audiophiles with very good main systems have a computer with a Lynx sound card? My PC twoer has an M-audio 2496, which ain't too shabby. However, I don't even use that for most audio listening. If they record live, maybe. Otherwise, probably not. I'm talking about ordinary people with ordinary computers doing a computerized ABX or ABC/hr test as per the POV expressed here that that is somehow superior to listening on one's main high-end system. I suggest if that bothers you, to run your computer output through your main 'high end' system and asses the background noise levels. And then test yourself with mp3s vs source ABX of increasing bitrate, starting down near the bottom. If you're *really* interested, that is. -- -S We have it in our power to begin the world over again - Thomas Paine |

Please explain what you mean about "bathed in digital noise from a PC". How does such noise sound? It sounds like a buzzing that varies as the programming changes. I've heard it from older (8086) PCs. It could be picked up on nearby unshielded electronics. It existed. It no longer does; I've never heard it from, modern PCs, even ones with cheap built-in audio. I have heard, however, serious ground loop problems from such PCs, cured by the usual audio ground loop cures. The real problem with my current setup is the Comcast cable line that feeds my HDTV and computer Internet; all the audio, video, and computer stuff is connected together. The cable connection causes a terrible hum, really bad. This was cured only by breaking the DC/audio connection between the cable and the cable modem and cable HD recorder boxes by adding 0.001 microfarad capacitors in both the center lead and shield to break the DC connection.

Norman Cell biology, if you want to be picky, though my training was really more in molecular developmental neurobiology; where I was, they didn't have a degree with that name at the time. While were at it; Biochemistry, Biology, Cell Biology, "whatever", the department's name was written on my diploma and it reads "Department of Micriobiology". Not that anyone is required to work in an area named on a diploma, which is just kind of a 'union card'. Since when did precision become picky? Norman M.
